NON-GELLED POLYAMINE-POLYEPOXIDE REACTION PRODUCT AND USE AS ELECTRODEPOSITED COATING COMPOSITION

摘要

A non-gelled amine-epoxide reaction product and acid addition acid addition salts thereof where the product is obtained by co-reacting; a) a secondary amine NHR1R2, wherein R1 and R2 the same or different are C2 or C3 hydroxyalkyl groups, b) a polyepoxide, c) optionally a polyoxyalkylene polyamine, d) a product of the reaction between an epoxide with at least two epoxy groups and which contains less than 40% by weight of aromatic groups, and an amine of formula (1): NR3R4(CH2)nNH2 (1) in which n is from 2 to 6, and where R3 and R4, the same or different are methyl or ethyl, and optionally, e) a monoepoxide the components of product (D) being chosen so that the non-gelled amine epoxide reaction product is a liquid at temperature above -5 DEG C.
